MSD Project Clear is the initiative to improve water quality and alleviate many wastewater concerns in the St. Louis region. It will invest billions of dollars over a generation in planning, designing, and building community rainscaping, system improvements, and an ambitious program of maintenance and repair.

FOG accumulation in the public sewer system from holiday cooking can cause blockages in the sewer pipes, which then keeps the pipes from functioning properly.

Project Clear By the Numbers

MSD Project Clear involves significant work across the Saint Louis City and County area, to build system improvements, repair and maintain the existing system, and to get excess rainwater out of the system.

Get the Rain Out

MSD Project Clear gets the rain out of our system by managing rainwater where it falls.

System maintenance and rehabilitation have been a part of MSD’s operations for many years. MSD Project Clear continues this work on an accelerated schedule as part of other system improvements.

System maintenance and rehabilitation is critical to MSD Project Clear’s commitment to quality customer service, and to MSD’s mission statement: “To protect the public’s health, safety, and water environment by responsibly providing wastewater and storm water management.”

In addition to removing excess rain water from the sewer system and repairing and maintaining the existing system, new construction is necessary to meet the wastewater needs of MSD’s service area.

Project types may include new sewer lines to convey additional wastewater, constructing above-ground wastewater storage tanks, or installing deep underground tunnels to both store and convey additional wastewater in times of high service demand.
